If I'm correct that the data center shown is on Belfort and Glenn Dr, then you don't even have to "research" zoning, just look across the street.

In 2021/2022 before it was built:

* Here is what that lot looked like [1]. To assume something wouldn't be built there is optimistic at best. (And there was precedent for data centers at the time - there was already a data center less than half mile away on Vantage Data Plz across the street from Tart Lumber.)

* If you look across the street, ie if the video would have panned to the left, you would have seen the "US Customs and Border Patrol" building - not winning any architectural design awards [2].

For someone who bought their house decades ago, then yes - the area has transformed drastically. But grouping someone who purchased recently with someone who purchased decades ago is a bit muddled.
